Defectivehardware or firmware can cause the adapterto indicate a
self-test failure as follows:

HThe indicators light and remain amber
HThe LAN-Link, LAN, and GPIB indicators blink red after the
self-test at power on.

AD007adapter
3. If indicators light, wait 30 seconds for the sel f-test to complete.
Blinking indicators at the beginning of power on indicate t hat the
hardware self-test is in progress.
4. Toindica te a successful self test, the LAN-Link, LAN, and GPIB
indicatorssimultaneously blink green before automatically
starting the LAN discovery (DHCP/BOOTP request) loop. See
Table2.
5. Toindicate a hardware failure in the adapter,the adapter will
indicate one or more of the following
a. The LAN-Link, LAN, and GPIB indicators simultaneously
